PSG has now secured the season-opening cup on fourteen different occasions.
The Parisian giants needed a stoppage-time leveler followed by a perfect penalty shootout to overcome their arch-rivals in the Gulf and capture a fourth straight French Super Cup title.
The European champions appeared to be sailing towards a straightforward win in the showdown between the French league winners and the French Cup holders after Ousmane Dembele found the net in the opening stages.
Yet, the southern French side fired two times in the closing moments to seize a surprise lead. First, Mason Greenwood scored from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a breathtaking twist of fortune, the Portuguese striker grabbed a vital leveler in the final moments to send the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, stopping decisive attempts from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all scored with composure for PSG to seal a convincing shootout victory.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this trophy for the twelfth time in the past 13 years.
